citizen ofthe United States,

To 522 mm it may 00mm; Be it known thatI, Louis residing at New.

York, in the cou nty of New-York and State ofNew York,have inventedcertain new and. useful Improvements in Demountabl R1111s and I do hereby declarethe following tobe a full, clear,'a'nd exact description .otthe in-' vention, such as ,will enableothersskilled 1n, the art to which it"appeitainstosmake and use thesame. v

p Th s invention relates to improvements 1n 7 demountable rims of the type knownasand the ,primaryobject in view' is the adaptation of the rim-"130;, receive a;

cross-cut manipulating tool.

The particular type of 'tool{ adapted for use in'manipulating the present improved rim is illustrated and claimed-in-{iny 00-" pending application filed August 16, 1917 SerialjNo'.-186',524, and will, therefore, be.

described only very briefly' so as to r'eiider clearthe utility of the cooperating parts offl the rim. a In the aceompanying' draw.1ng, 1

F igure 1 1s a side elevation of "a fragment of a rim embodying the features ofthe'pres- 'ent invention, the, operating" tool ,b in

shown in position thereon.

Fig. 2 is a perspective view o'f a similar fragment of the rim, the tool being omitted.

F ig. 3. is airagmentary plan view on an enlarged scale of that portion of the rim provided with the tool-receiving plate.

Figs. 4 and 5 are verticalisections taken respectively on the planes indicatedby lines 4i i and 5-5 of Fig. 3.

Fig. 6 is a perspective view of the operating tool detached.

Fig. 7 is transverse section taken on the plane indicated by line 7-7 of Fig. 2. V

Fig. 8 is a sectional view similar to Fig. 4

a slightly modified embodiment.

Fig. 9 is a view similar to F igl 3 showing a slightly modified form of plate.

An extension handle 20 is 10551,

in dotted lines in Fig.3, whereupon the ends of the button 12 willhave been swung beneath the overhanging part 7 of plate 6, as indicatdby the-dotted lines at 12 in Fig. 3. The fulcrum post 11 will thus be efl'ectivelyanchored' to the rim and'the'hooks 17 are'then inserted through the eyes21 and nut 19 tightened up for drawing the links together 'sufliciently "for preventing accidental escapeof the hooks from the eyes. The lever handle 20 is then grasped by the operator and swung through an arc to a position at the opposite side of the "fulcrum 11 from that shown inJFig. 1, during which movementthe links 15 effect a lifting of their engaged end of the rim 0,1? freeing it from latch 4, and then a movement toward (enable application and removal of a tire 'havin inextensible beads. P Fig. 8, Ihave shown aslightly modi-j' field embodiment wherein the parts are iden the post 11 to an extent sufficient for causing therequired collapsing of the rim for reducing the efifective diameter thereof so as to tical with those above described with the exception of the form of the under face of 5 l the button. The button is seen at 12 and 5: The other parts are identical with thosede-' is provided with a parti-globular under face,

as indicated at 12". The rim 1 is formed with a "parti-spherical depression 7 for snugly receiving the parti-globularface 12" scribed and the same reference numerals have been applied with the understanding thatthe same description may also be applied. I The anchoring plate for receiving the fulcrum post may be fastened to the rim invarious ways, such as by welding or rivet- .ing, and, may assume various contours as, a for example, instead of being rectangular, 1 "as seen in Fig. 3, it may be tapered in opposite directions, as indicated in Fig. 9. In

thisfigure the rim 1 is provided with the plate 6' having tapered ends with only two 1 points of attachment. The structure; is

otherwise identical with that seen in Fig. 3. What is claimed is 'f f 1. The'combinatio'n ofja cross {out de- .55 mountable rim and .atool-receiviiig plate connected with the. rim and having a slot withlateral enlargements adapted to aceom- I modate the passage of a post ofgreater'cross section than the width of the main portion" of'the slot, while leaving outstanding portions of the slot, a portion of the'plate spaced from the rim.

2. The combinat'on of a cross-(cut de mountable rim and a plate. fixed theretofa'nd having a button'receiving opening,ithe"rim being formed with a parti spherical recess} in line with the opening for snuglylreceiv I 7 .ing a globular-portion of a button;

3. The combination of a cross cutdemountable rim and a tool-receiving plate 1 connected with the inner face of thejrim and having an elongated ,slot, the slot being,

formed intermediate its ends with curved lateral enlargements for accommodating the,

passage of the cylindrical portionof atool of greater diameter than. the width of the slot, the plate having portions'spaced ini V ward from the inner face of the rim for accommodating a projection from such post between the plate and rim.

In testimony whereof I ffix my signature in presence of two witnesses.
